SECURITY ALGORITHM  
Identification of a security algorithm.

Dependency Notes:
1. D5(030, 020) If first, then all
2. D5(050, 040) If first, then all
3. D5(020, 040) If first, then all
4. D5(070, 060) If first, then all
5. D5(060, 040) If first, then all

Notes:
6. 0533, a mode of operation shall be chosen in relation to the chosen algorithm (data element 0527). Some combinations of mode of operation and algorithm are not appropriate.
